i have read and studied most of the forums on wind calculation, rulers, effect on distance but have not seen any comments about consistency of the wind. when the wind indicator says "19-21" does that mean the wind is constantly blowing within that range? or does the wind change strength during the game/hole? does the wind sound effect denote when the wind is blowing? in my play it seems to me that sometimes when i allow for the wind there is no effect on the ball flight. it would be helpful if there was some sort of deciphering whether the wind is at the noted strength or if there is lull in the wind, like in real golf. thanks in advance for your thoughts and suggestions.
